Hi all!
I m modeling flow and heat transfer in a heat exchanger model. After convergence of a simulation (or even during the simulation), i would like to caculate the temperature gradient at any point of the computational domain. I have tried to have a look at the User guide for the implementation of user Fortran code into Star CCM+ but the examples found concern only very simple user profile codes. Could anyone help me please? Coolio Last edited by coolio; July 26, 2010 at 03:16. |

Sorry!
I found a solution! I was using an old version of the software! After updating to the new release (5.04), i found many derivative operators! Regards! |

can you tell me how did you adapt the derivative operator in the STAR-CCM+?
thank you very much, my email is 54acan@gmail.com |

The field function "grad($Temperature)" provides you the gradient vector of temperature for your given coordinate system.
If you are just interested in the magnitude value of the gradient vector just use "mag(grad($temperature))". Last edited by willimanili; December 22, 2011 at 02:09. Reason: changed abs to mag |

I want to take dot product of gradient operator and unit normal vectopr for this i need to take just gradient operator so is it like "grad" only or $$grad please help?
thanks krishna. |
